VAPOR-BURNING STOVE.

SPECIFICATION forming part of Letters Patent No.-414,736, dated November 12, 1889.

Application filed July 5, 1887. Serial No. 243,309. (No model.)

.To (ZZZ whom it may concern.-

Be it known that I, HENRY M.VAUGHAN, a citizen of the United States of America, and a resident of Newton, in the county of Jasper and State of Iowa, have invented an Improved Vapor-l-iurning Stove, of which the following is a specification.

My object is to prevent the dangers and accidents incident to the use of vapor-burning stoves, to improve the construction and operation of vapor burning sieves in which volatile fluids are carbureted by means of mechanism for forcing and mixing air with the hydrocarbon vapor before it is admitted to the burners, and also to provide a means for signaling to the attendant when the reservoir containing the fluid is nearly empty and a fresh supply of liquid fuel is required to continue the operation of the stove.

My invention consists in the construction and combination of a liquid-reservoir, a fan, and an automatic signal, as hereinafter set forth, in such a manner that all of these elements will be compactly united at the base portion of the stove and readily put in operation and continued in operation and controlled by a person of ordinary intelligence.

Figure 1 of the accompanying drawings is a vertical sectional view showing a fan and fan-operating mechanism combined with an air-tight reservoir. Fig. 2 is a sectional view and modification of Fig. 1, showing an automatic alarm combined with the fan-operating mechanism. Fig. 3 is a side view of a complete stove, and Fig. at a side view illustrating the construction and operation of the detent for operating the alarm mechanism at a stated time.

A'is the top, and B the burners, of a stove of common form.

0 represents a case in which a carburetor is inclosed and fixed to the stove.

d d are tubes extending from the burners B into the top of the reservoir to conduct carbureted air from the reservoir to the burn ers. Stop-valves d are applied to burners or tubes to stop the passage of the carbureted air at pleasure.

F represents an air-tight reservoir that may vary in shape and size as desired.

ing air with kerosene or other heavyoils this tube is made to terminate near the bottom of the reservoir.

J is a fan-shaft, and J a drivingshaft connected therewith by means of gearing in such a manner that power and motion can be transmitted from the drivingshaft to the fan at pleasure by means of springs or other suitable motors, as required, to actuate the fan and to force air into the air-reservoir, to be carbureted therein from contact with volatile liquid in the reservoir. In Fig. 2 the driving-shaft J 2 is shown tubular, and a solid shaft extends through, to be operated automatically as an alarm device when the driving-shaft has made a given number of revolutions and the liquid in the reservoir is nearly exhausted. The driving-shaft J 2 and the shaft 7t have square outer ends, upon which keys can be placed to rotate them independently, as required, to store power in the springs connected therewith.

Z are hammers fixed to the shaft k in such a manner that they will strike a bell m that is fixed inside of the fan-chamber.

a is a spring fixed to the shaft at one of its I ends and to the case at its opposite end in such a manner that power can be stored in the spring by rotating the shaft by means of a he n is a ratchet-wheel fixed to the shaft 10.

0 is a detent pivoted to the case in such a manner that it will in its normal condition by force of gravity engage the ratchet-wheel and lock the shaft.

p is a toothed Wheel, and r is a cam on the end of its axle that will operate the detent at each complete revolution of the wheel, as required, to free the shaft kso it will rotate Loo and make the hammers Z strike the bell continuously until the force stored in the spring is exhausted.

s is a cam on the tubular driving-shaft J, that engages the teeth of the wheel succcssivcly, as required, to impart intermittent motion to the wheel, so that it will make a complete revolution in any given time desired, as required, to start the alarm when the supply in the reservoir is nearly exhausted. As the oil-reservoir may vary in size, the capacity of the fan and the spring for operating it must also vary, as required, to correspond with the reservoir, so that when the reservoir is filled and the spring wound up the number of revolutions of the driving-shaft will be proportioned to the time required to exhaust the reservoir, so that the alarm combined with the driving-shaft will be operated before the reservoir becomes empty.

In the practical use of my carbureted-air stove, when gasoline or other volatile combustible fluid is placed in the reservoir, I wind up the springanotor and start the fan to force air through the fan-chamber into the air-tight reservoir, and then open one or more of the stop-valves in the tubes extending to the burners to allow the earbureted air to escape and to be lighted with a match in the manner that common illuminating-gas is distributed and burned. Culinary vessels are then set over the burner in a common way and heat generated under them by means of the carbureted air, and continued as long as re quired,or until the supply of the combustible liquid in the reservoir is exhausted.

I am aware that a hydrocarbon-chamber of peculiar construction and a chamber contain- 1 ing air-forcing mechanism have been attached to a stove at different points and connected with each other and with burners by means of tubes; but my mannerof constructing and combining a reservoir, a fan-chamber, a fore ing mechanism and alarm mechanism with a stove is novel and greatly ad 'antageous in that the tube that conveys air from the fan to the reservoir and all the fan-operative mechanism is concealed and combined so that they can be jointly attached to a stove at one point at the base to improve the appearance'and eflicieney of a hydrocarbonstove. The automatic alarm mechanism is also concealed and'advantageous in the com bination in that it will give notice to an attendant before the oil is exhausted, so the rcservoir can be again filled before the tire is extinguished and the cooking operations interru pted.

I claim as my invention- 1. The combination of a reservoir, a fanchamber, a tube extending upward from the fan-chamber through the reservoir and tcrminating and concealed therein, a rotary i an, and mechanism for operating the fan with a vapor-burning stove, in the manner and for the purposes stated.

2. The combination of a reservoir, a [anehamber, a tube extending from the fan-chamber upward through the reservoir and terminating and concealed therein, a rotary fan, mechanism for operating the tan, and an automatic signaling or alarm mechanism with a vapor-burning stove, to operate in the manner set forth, for the purposes stated.
